COMET C/2002 P1 (NEAT)}
     Further observations made of this comet during Aug. 10.4-10.9 UT are
included on MPEC 2002-P46, together with the following very uncertain
parabolic orbital elements:

     T = 2001 July  7.85 TT           Peri. = 339.32
                                      Node  = 312.57    2000.0
     q = 7.0989 AU                    Incl. =  43.38

     Further to IAUC 7951, D. Hammer reports measurements for comets
detected on C2 SOHO website images by R. Kracht (C/2001 K11 and V6, Meyer
group; C/2001 Q8, R8 and R9, Kracht group--see MPEC 2002-E18, 2002-E25,
2002-F03, 2002-O35), M. Oates (C/2001 L10, R7 and X10, Meyer group) and X.
Leprette (C/2001 L11, Kreutz group).  The reduced astrometry and orbital
elements by the undersigned appear on the cited MPECs.

SUPERNOVA 2002eg IN UGC 11486
     A. V. Filippenko, R. Chornock, R. J. Foley, W. D. Li, M. Papenkova and B.
Swift, University of California, Berkeley, report that inspection of CCD
spectra (range 310-1000 nm) obtained on Aug. 9 UT with the Shane 3-m reflector
at Lick Observatory reveals that SN 2002eg (IAUC 7944) is of type IIb, shortly
before maximum brightness.  The spectrum is very similar to that of SN 1996cb
on 1996 Dec. 27 (Qiu et al. 1997, A.J. 117, 736), about 6 days before B-band
maximum; specifically, the Ca II near-infrared triplet is extremely weak or
absent, whereas it was present in SN 1996cb at earlier and later epochs.
